SPECIFICATION forming part of Letters Patent No. 435,956, datedSeptember 9, 1890.

Application filed March 6, 1890- Serial No. 342,891. (No model.)

To all whom it may concern:

Be it known that I, GEORGE \V. Vi- ALLING- FORD, a citizen of the UnitedStates, residing at Mount Gilead, in the county of Mason and State ofKentucky, have invented certain new and useful Improvements inOar-Couplings; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to car-couplings; and it consists in the novelconstruction and combination of the parts hereinafter fully describedand claimed.

In the drawings, Figure 1 is a sectional plan view of the device,showing the two halves of the coupling coupled together. Fig. 2 is afront view of one half of the coupling, showing the disengaging devices.Fig. 3 is a side view showing the two halves of the coupling beforebeing pushed together.

A is a hollow block adapted to be secured to one end of a car andprovided with the buffer-pieces a in front for striking against theother half of the coupling.

13 B are two bars provided with hooks b at their front ends, and b is apin which passes through the block A and through the rear ends of saidbars.

O is a single spring, which has a central part coiled about pin b andhas its ends firmly secured to the two front ends of the bars B B. Thisspring presses the hooks apart and causes them to bear against the stops0 at the front end of block A. This construction permits the back ofeither hook to be pressed over against the other, or the backs of thehooks may meet in the center if the pressure on both sides is appliedequally. It will be seen that the spring is not weakened by rivet-holesand fastenings.

b are inclined or pointed portions on the front ends of the hooks, sothat they may engage automatically with the other half of the coupling.

D is a block adapted to be secured to the opposed'end of the next car.This'block is provided with the central hole D, having beveled sideedges 01 for the portions 1) of the hooks to strike against andshoulders cl behind said beveled portions for the hooks to engage with.When the cars are pushed together, the hooks are pressed toward eachother until they pass through the holeD'. The spring 0 causes the hooksto engage with the shoulders as soon as the hooks are through the hole.

E is a locking-tongue provided with a rod e, and E is the guide forthesaid rod secured to the block D.

F is a loop formed in the upper part of rod 6, and F is a bracketadapted to be secured to the end of the car and provided with threesteps f. Then the cars are coupled, the rod e is lowered until the looprests upon the bottom step and the tongue is held between the hooks,thereby preventing them from being pressed together and becominguncoupled from the shoulders.

. G G are two plates pivoted at their bottom edges on the pin g underthe middle of the hole D of block D.

H are inclined rods, which are pivoted to the arms g, which project fromthe plates G, and the said rods are provided with eyes h at their upperends for the rod e '30 pass through.

H is a stop upon the rod 6 for engaging with the eyes h. When the carsare to be uncoupled, the rod 6 is raised and the loop passed over thetop step or hook of the bracket F. During the first half of its upwardtravel the rod 6 merely raises the locking-tongue from between the hooks1), thereby permitting them to be pushed together, and the rod may beheld in this position by passing the loop over the middle step or hookf. When the rod 6 arrives at its middle position, thestop H meets theeyesh, and during the second half of its upward travel the said rodraises the inclined rods H and turns the plates G upon their pivot. Theverticalportions h of said plates press together the hooks b, so thatthey may pass rearwardly through the hole D. The plates are restored totheir original position and the tongue is held in its middle posit-ionby lowering the rod e until the loop F engages with the middle step orhook f, when the parts are again in position to be recoupled. The rod 6may be worked from the roof of the car or from either side of it in anyapproved manner.

lVhat I claim' is- ICO 1. In a car-coupling, the combination,with ablock provided with a central hole having beveled front edges andshoulders behind said edges, of a hollow block provided with a verticalpin, two bars having their rear ends pivoted on said pin and havingpointed hooks at their front ends for engagingwith the said central holewhen the blocks are pushed together, and a single spring coiled aboutthe said pin and having its ends firmly secured to the said bars,substantially as and for the purpose set forth. 7

2. In a ear-coupling, the combination, with a block and two projectingspring-actuated hooks pivoted therein, of a block provided with acentral hole and shoulders for said hooks to engage with and avertically-movablelocking-tongue adapted to he slid between the ends ofthe hooks; substantially as and for the purpose set forth.

3. In a car-coupling, the combination, with a block and two projectingspring-actuated hooks pivoted therein, of a block provided with acentral hole and shoulders'for said hooks to engage with, the platespivoted at their bottom edges to a pin under said hole and provided withVertical portions at each side of the hole, and rods for turning saidplates simultaneously on their pivot and thereby detaching thecoupling-hooks, substantially as and for the purposes set forth.

4. In a car-coupling, the combination, with a block and twospring-actuated hooks pivoted in said block, of a block provided with acentral hole and shoulders for said hooks to engage with, thedisengaging-plates pivoted under said hole, the inclined rods providedwith eyes at their upper ends,- the lockingtongue, the rod for raisingsaid tongue provided with a stop adapted to engage with the said eyesand to actuate the disengagingplates when the locking-tongue has beenwithdrawn from between the coupling-hooks, and a stepped bracketadaptedto support the said rod at different positions; substantially asand for the purpose set forth.

In testimony whereof I affix my signaturein presence of two witnesses.
